OIL-PUMP.

SPECIFICATION forming part of Letters Patent No. 233,231, dated October 12, 1880. Application filed February 24, 1880.

To all whom it may concern:

Be it known that we, HARVEY F. GASKILL, of Lockport, in Niagara county, New York, and J. G. BENTON, of Titusville, in Crawford ;county, Pennsylvania, have invented certain Improvements in Oil-Pumps, of which the following is a specification.

Our invention relates to pumping-machines, and is more especially designed for use on pipe-lines where oil is pumped through a long line of pipe. It is obvious that on a line of any length the pipe must contain an enormous weight of oil, and that if this oil be forced through the pipe in pulsations, as is the case 1 with ordinary pumps, there must be an enormous loss of power in overcoming inertia alone. By our invention we overcome this objection and avoid this loss, and can therefore pump a greater quantity of oil, or pump through a longer line, with an engine of given power than can be done with ordinary pumps; and this we do by combining one pump-cylinder with two other pump-cylinders at an angle of one hundred and twenty degrees from it, and op- 2 crating all three cylinders from two cranks, which make an angle of one hundred and twenty degrees with each other, as will be more fully explained in connection with the drawings. The effect of this arrangement is that the oil is delivered from the pumps in a steady stream of uniform velocity, and without substantial variation of pressure. In the full-sized pumps which we have built we have found a variation in the oil-pressure of less than five pounds when pumping against a pressure of six hundred pounds, and we have successfully operated our pumps in pumping oil through a line of seventy miles in length.

In the drawings, Figure I is a side elevation of one of our pumps. Fig. II is a top view of the same; and Fig. III is a diagram of thecranks and connections, &c.

A is the main shaft from which the pumps are driven. B B are two cranks on the ends of this shaft located at an angle of one hundred and twenty degrees apart. K K K are cross-heads moving in guides L L L on the frame D, and connected with the two cranks, B B, by the connecting-rods O G O. H H

are two pump-cylinders supported by the frame D at an angle of one hundred and twenty degrees from each other, and both operated from the same crank B by means of the connecting-rods as shown.

Parallel with H, and on the opposite side of the frame D, is a third pump-cylinder, H, which is operated from crank B by means of connecting-rod O", as shown. The strokes of the pumps are thus perfectly timed with the effect previously mentioned.

On the middle of shaft A is a spur-wheel, E, with which gears a pinion, F, on shaft G, as appears in Fig. I. We have, however, for simplicity, omitted most of the cogs from the drawings. The pumps are driven by power 6 applied to shaft G, and transmitted to the cranks through pinion F and spur-wheel E.

I0 is the pipe-line. it" 1' are three branch pipes, one for each pump-cylinder, through which the oil is drawn by the pumpsfrom the 0 main pipe I. o o o are three branch pipes through which the oil is forced by the three pump-cylinders into the main line 0.

Having thus described our invention, we claim 1. In an oil-pump, the combination of the frame D, the pump-cylinders H H, supported thereby at an angle of one hundred and twenty degrees apart, the crank B operating said two pump-cylinders, the crank B, and the pumpcylinder H, operated thereby, each and the whole constructed and operating substantially as set forth.

2. In an oil-pump, the two cranks making an angle of one hundred and twenty degrees with each other, one of said cranks operating two pump-cylinders, which make an angle of one hundred and twenty degrees with each other, and the other of said cranks operating a third pumpcylinder, which is parallel to one 0 of said first two cylinders, in combination with. said three pump-cylinders for the purpose of pumping with a substantially uniform pressure and velocity, and without pulsation, into a pipe-line, substantially as de- 5 scribed.
